pool accumulates new zero-size files, all of which were produced by a failed TPC-Pull transfer (from different remote sites) that ended with return code 10027.

The 10027 code is a generic ThirdPartyTransferFailedCacheException. The exception's message might reveal more information on what is going wrong with the transfers. This should be logged in billing and possibly in the pool's log file.

The door should clear up any failed transfers, so it would also be interesting to see the door access log file for these transfers.
